Thank you, Andygc. It’s not of English-speaking origin. The original text is in Chinese.No. "In" would do, but the sentence as a whole seems a bit odd for medical English. You have not told us if this is of English-speaking origin.
I think you could use either, but I’m sure Andy will be able to tell you what’s more common or if there’s something better.Thank you again, ripper.
By the way, why do you use the singular “abnormality” after “no”? Doesn’t “abnormalities” work?
